Ryuunosuke Mochisuki is a plain, overworked salaryman. After completing a three-month long project, he struggles to make his way back home from work and dies of exhaustion en-route. Fortunately, luck is on his side and he reincarnates into an adorable mochi monster with overpowered stats and crazy cheats. He could take over the world with a jiggle of his glutinous belly but... he's just too lazy! And so his life of sleeping, eating, and leeching off the Demon King begins!
